Open Source EMDR Machine. The Whole Blog.
This will be a quick update:
While working correctly initially, at some point tappers (vibration motors) stopped working as designed.
After frying two relay modules I think I found the t...
Design for a Cause 2021 - Robotic Hand (Blog #7) – Project Complete (Part 2) As promised, here is the video of the working hand. But first: Issues I had making it work:Calibrating it properlyI had problems with the calibration due to ...
I had planned a lot to be done on this project but in fact it turned out to be an ambitious one. Ambitious because in these 3 months, a lot has happened. I have a full-time job and very busy family with one expecting soon! I can't believe how time ha...
I didn't want to damage Arduino Nano 33 IoT board and I didn't know what signals were appropriate for the motors and their wiring diagram etc., for the motors that I salvaged from and office printer. So, to avoid any mishap, I used my Arduino Uno to ...
OK, I will be honest. When I finished, it looked more like a stool than a chair My 3 year old called it a table ! But anyways, let me show you how I built it. This chair needs to have wheels so that it can be driven around on flat surfaces in h...
Arduino Nano 33 IoTI was very excited to receive Nano 33 IoT! I opened the package and was surprised by the size of it and how much flexibility it delivers, mainly WiFi, Bluetooth and IMU, all on the same board. This makes it perfect for virtually al...
Hello! Today is the last day of the building period of Design For A Cause 2021 , so I will summarize what I managed to do and what can still be done in the future The scope of the projectDevelop a prototype of an IoT device which can be easily ...
The hardware system is composed of Arduino Nano 33 IoT and micro-vibration motor(s). Arduino Nano 33 IoT Micro-vibration Motor The vibration motors will be interfaced with the GPIO pins of the Arduino Nano 33 IoT and ...
Design and build stand-up and walk aid - smartChair BackgroundAgeing is a process that affects us all. In particular, when old age strikes, many of us are affected with various health issues such as arthritis, continuous back ache, knee joint pa...

Due to lack of resources and long delivery time, I could not get off the shelf soil moisture sensor aka soil hygrometerSo decided to make one after understanding the principle of working. There are multiple ways through which we can measure the soil ...
So, in the previous blog, we discussed the problem statement that my project tries to resolve.Now, we will develop an Accident and Jerk Detection system to possibly find a solution to the discussed problem statement, ie to reduce motor accident morta...
The accelerometer data can be used to detect the minute vibrations during the elephant's walk or poachers vehicle or illegal deforestationetc.I would like to create 4 different models here to detect different scenarios.CLI tool showing that the d...
The Global status report on road safety 2018, launched by WHO in December 2018, highlights that the number of annual road traffic deaths has reached 1.35 million. Road traffic injuries are now the leading killer of people aged 5-29 years. The burden ...
This is the last blog of this challenge. So it's time to make a recap of what I learnt and what I would have done differently What I learnt TensorFlowFor sure, the most important topic I learnt during this challenge is TensorFlow. It'...
